C# 使用 AutoResetEvent 或 ManualResetEvent 同步两个线程

             //Thread read = new Thread(new ThreadStart(ReadMethod));
             //read.Name = "Read Thread ";

             //read.IsBackground = true;
             //read.Start();

             // 如果使用线程池方法的时候.线程都是 后台线程. Console 会立即结束.所以需要这个方法来阻塞主线程
             Console.ReadKey();
         }
     }
